GEORGE S. GRAY, OF BELOIT, WISCONSIN.

NUT-LOCK.

Specification of Letters Patent.

Patented May 14:, 1907.

Application filed August 7,1906. Serial NO- 329,594.

T0 60% whom it may concern.-

Be it known that I, GEORGE S. GRAY, a citizen of the United States,residing at Beloit, in the county of Rock and State of VVisconsin, haveinvented certain new and useful Improvements in NutLocks, of which thefollowing is a specification.

The object of this invention is to provide a device to be placed betweena nut and a suitable support which will prevent the loosening of thenut.

In the accompanying drawings, Figure 1' is a side elevation of myimproved nut lock before pressure is brought to bear upon the parts.Fig. 2 is a similar elevation in which the parts are firmly seated. Fig.3 is a plan view of my improved nut lock. Fig. 4 is a vertical sectionon dotted line a a Fig. 3. Fig. 5 is a similar section, but in which thegripping plate is depressed. Fig. 6 is a perspective view of thegripping plate.

My improvements consist of the open ring 1, having its ends 2 and 3beveled, and eX- tending parallel with one another. A gripping plate 4is rectangular in form, and is provided with two grooves 6 and 7 locatedin opposite faces of the plate. These grooves are cut diagonally throughthe plate as shown at Figs. 4, 5 and 6 and leave two edges 5 and 8 full.The plate 4 is of steel and hardened.

' The gripping plate 4 is placed in connection with the ends of the ringby an end located in one of the grooves.

The bolt 9 is passed through the support 10. The ring 1 with thegripping plate 4 in connection therewith is placed over. the projectingend of the bolt and a nut 11 is turned down against the gripping plateas shown as Fig. 2. The pressure of the nut against the gripping platewill tend to place the plate into nearly a horizontal position. The openring will yield to permit the gripping plate to assume this position.The action of the spring of the rln is to hold the gripping plate in theposition s own at Figs. 1, 3 and 4 but will yield when pressure isbrought to bear against the plate as shown at Figs. 2 and 5. The edgesof the gripping plate will sink into the face of the support 10 and theinner face of the nut 11, when the nut is turned in a direction toloosen it.

By this construction of nut lock, it Will be impossible to remove thenut without breaking or destroying the look.

I claim as my invention.

1. A nut lock comprising an open ring and a grippingplate locatedadjacent and diagonal to the ends of the ring.

2. A nut lo'ck comprising an open ring and a gripping plate supported bythe ends of the ring in a diagonal manner.

3. A nut lock comprising an open ring and a gripping plate, the ends ofthe ring located diagonally and the gripping plate having diagonallyarranged surfaces receiving the ends of the ring.

4. A nut lock comprising an open ring and a gripping plate, the grippingplate having grooves extending diagonal to its length and within whichthe ends of the ring are located.

5. A nut lock comprising an open ring, and a gripping plate supported bythe ends of the ring, and located diagonally to the ring.
